[torqueusers] Maui QOS

Thanks for the hint about checkjob.  I hadn't specified the QDEF on the CLASSCFG or GROUPCFG.  I added both, and now I'm getting the expected quality of service and priority.

Try this:

-W x=QOS:med

and then when the job is running do a "checkjob" on it to see that
you are getting qos you want.

I'm having trouble getting the Maui QOS to work.  I started by following the example in the admin doc and I've experimented to to no avail.

My QOS related variables in maui.cfg currently look like this:

QOSWEIGHT 1
QOSCFG[low] PRIORITY=1
QOSCFG[med] PRIORITY=10
QOSCFG[high] PRIORITY=100

I submit my jobs with qsub -W x:qos:med somejob

The syntax I saw in the archives had "-W x:QOS:med", but when I try that, none of my jobs run.  As it is I have a test case that submits a bunch of low priority jobs followed by a high priority job.  Each job grabs half the nodes, so the first two start running and the rest go in the queue.  When a job finishes, the processing continues in FIFO order rather than the high priority job getting taking precedence.

Any hints on how to debug would be appreciated.  I've looked at "diagnose -Q", but it doesn't tell me much.  I am using xpbs to monitor the queue.
